摘　　要：在基于射频识别(RFID)技术的煤矿井下无线通信系统中,由于井下人员和设备均配备电子标签(Tag),且共用信号频率和信道,相互间必然存在信道争用问题,同时信号传输也受到外界环境的干扰。从频率选择和防碰撞算法出发,分析研究该问题,指出需根据煤矿井下人员和设备的标签数量、瓦斯数据的传递量选择频率和防碰撞算法,为保障煤矿井下安全管理提供了新思路。In the application of the underground wireless and communication system based on radio frequency identification （RFID） technology in coal mines, the underground persons and equipment are all equipped with electronic tags, which shared the signal frequency and channel, so there must be channel contention, and the signal transmission might be interfered by the external environment. This paper, starting from the frequency choice and anti-collision algorithm, analyzed this problem, and pointed out that the frequency and anti-collision algorithm should be chosen according to the number of the underground persons and equipment with the electronic tags and the transfer amount of the gas data, this thus provided a new thinking for coal mine safety management.
